ATONIIZER FOR VENTILATING APPARATUS.

VIO

Be it known that I, EMIL OEHLMANN, of the city of Berlin, Kingdom ofPrussia, German Fmpire, have invented certain new and usefulImprovements in Atomizers for Ventilating Apparatus, of which thefollowing is a specification.

My invention relates to certain improvements in atomizers forVentilating apparatus, whereby the air introduced into closed orpartlyclosed spaces is moistened by finelydiffused vapors of water orother liquids.

In the accompanying drawings, Figure l represents a side elevation of myimproved atomizer with a part broken away. Fig. 2 is a plan of thejet-nozzles; Fig. 3, a top view of the atomizer. Figs. 4 and 5 are aside elevation and a plan of a modification ofthe atomizer. Figs. 6, 7,and 8 represent other modications. Fig. 9 shows the atomizer located inthe air-duct of a Ventilating-shaft; and Figs. 1() and 11 show thearrangement of the atomizer in connection With a cylinder,blowing-engine, and ordinary fan.

Similar letters of reference indicate corresponding parts.

The atomizer, Figs. 1, 2, and 3, consists of a branched water-supplypipe, a, which is connectedat c with the source of supply. b b arevjet-nozzles,l which are connected to the pipes a, and which may beprovided with valves or stop-cocks. d d are convex deflecting-plates,which are arranged vertically above the jet-nozzles b b, and supportedon a frame, c, of suitable construction. The face of the convexdeflecting-plates d is preferably made parabolic, so as to effect themost perfeet breaking up of the jets thrown against the deectors intospray or vapors. When water or other liquid under pressure is admittedinto the pipe a, it is discharged through the nozzlesb in thin jets,which impinge against the plates d, whereby the liquid is broken anddiffused. When the atomizing apparatus is placed into the air-duct of aVentilating apparatus, through which duct a strong current is forced bya screw-fan, as indicated in Fig. 9, or by a blowing-engine, as in Fig.10, or by an ordinary fan, as in Fig. Il, or by any other air-forcingdevice, the current carries off the fine spray or vapors along, so as todiffuse them in the spaces which are to be Ventilated. Owing to thebreaking up of the jets into vapors, the depositing of the moisture indrops is prevented. The air is thereby uniformly moistened, which is ofgreat importance for many purposes-as, for instance, in the manufactureof cotton thread, to prevent the breakingI of the fine threads. InVentilating hospitals the vapors may hold in solution disinfecting ormedical substances to be inhaled by the patients, and for this purposesea-water, salt-brine, or mineral waters may be used.

In place of a number of convex plates, d, Fig. l, a convex plate, cl, ofring shape, may be used, as shown in Figs. 4 and 5, in which case thepipe a is also made in the shape of a ring; or the pipe d may be madesquare, aS in Fig. 7, or curved, as in Fig. 8, the deflecting-platesbeing made to correspond there- With.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An atomizer for Ventilating apparatus, consistingof a supply-pipe having one or more jet-nozzles, and of a convexdeiiecting plate or plates arranged in line with the axis of the nozzleor nozzles, substantially as set forth.

2. The combination of the tubular frame, a water-supply pipe connectedthereto, aseries of jet-nozzles attached to said tubular frame,

and a convex deflecting plate or plates in` line with the nozzles `ofthe tubular frame, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

EMIL OEHLMANN.
